This study investigated the association among parental socioeconomic level, overweight, and eating habits with diet quality in Korean sixth grade school children. A 3-day dietary survey was conducted, and a questionnaire and anthropometric data were collected from the Korean child obesity cohort (320 boys and 345 girls). The children were classified into two groups (low or high level) based on monthly household income and paternal and maternal education status. Lower maternal education status was associated with a higher risk for overweight in girls (odd ratio, 1.91; 95% confidence interval 1.07-3.44), whereas belonging to a higher socioeconomic group in terms of parental income or parental education level resulted in the consumption of significantly more fruit. Boys did not show significant differences in the intake of most nutrients or diet quality regardless of socioeconomic status. However, girls in the lower socioeconomic group had a lower food habit score (higher frequency of breakfast skipping and ramen noodle consumption), diet quality, and intake of nutrients (carbohydrate, vitamin C, potassium, and fiber) than those in the higher socioeconomic group. Therefore future nutrition policies and interventions should support parents and children with lower socioeconomic status to develop health-related behaviors that may prevent childhood overweight.

Objectives : This study was to investigate the characteristics of the heart rate variability(HRV), types of insomnia and accompanying symptoms of 175 insomnia patients. Methods : For this study we carried out HRV, Inbody of 175 patients with insomnia who have come to Dongeui oriental hospital of Dongeui university from the period of Janaury 2008 to September 2010. We studied the association of the insomnia patients' age and gender with HRV, accompanying symptoms and the types of insomnia. The information of the accompanying symptoms and types of insomnia was based on each patients' progress note. Results : l. There was no significant differences in the characteristics of HRV between male and female. 2. The most frequent symptom shown among the insmonia patents' was headache(41.14%). 3. Comparing the symptoms between the gender, female patients had more dry mouth, alternative periodic chill and fever, and hot flush symptoms than the male patients. 4. Comparing the symptoms between the age groups(divided in two), the lower age group (20~59) had more dizziness and constipation symptoms than the higher age group (over 60). 5. Comparing the types of insomma between the age group, the higher age group (over 60) had more termination insomnia. 6. The types of insomnia of the entire insomnia patients were onset insomnia (73.1%), maintenance insomnia(20.6%), termination insomma(l7.1 %), shallow sleep (52.6%), listed by order of frequency. 7. The patients who takes hypnotics had more anorexia symptoms than the patients who doesn't take hypnotics. 8. There was no visible differences of the average fractal portrait between male and female. The age group of 20~30yrs. had the highest average fractal portrait, and the age group of 30~59yrs. the second highest, and the age group over 60yrs. the lowest. 9. The average of the regulation reserves of the autonomic nervous system(B2) - was lower than the regulation level of the ANS at the present (Bl). 10. When compared the priority of the function of the ANS, it showed that the proportion of HF($38.61{\pm}29.19%$)was the most, and than VLF($30.65{\pm}23.36%$), LF($20.04{\pm}19.13%$) the least. 11. The average of the compensation level of the central nervous system at present(Cl) - was lower than the compensation reserves of the CNS(C2). 12. The average of the control reserves of the cerebrum(D2) - was lower than the control level of the cerebrum at the present (Dl). 13. There was no visible differences between different sexes and ages in pulse rate. 14. The abdomen fat ratio above the line of the insomnia patients was 77.97% in male and 93.1% in female. Both sexes showed that insomnia patients had more abdomen fat that the standard, and female patients had more abd. fat than male patients. Conclusions : This study shows that the HRV of insomnia patients had no significant differences between gender. Fractal portrait, HF, LF and VLF of the insomnia patients are in inverse proportion to the age. The study of the Body Component Analysis showed that female had more abdomen fat than male, and both gender showed more abdomen fat than the standard. When looked into the accompanying symptoms of the insomnia patients, the symptoms show differences according to gender, age and hypnotics taking, as shown as below. In the entire patients, Headache was the most accompanying symptom. Female had more dry mouth, alternative periodic chill and fever, and hot flush symptoms than male. Higher age groups had more dizziness and constipation as accompanying symptoms than lower age groups. Patients who takes hypnotics had more anorexia than those who dont.

Purpose : Intravenous infusion of albumin has been widely und to relieve severe nephrotic edema in spite of beneficial or harmful effects. The purpose of this study is to examine the harmful effect of albumin on the clinical course of steroid sensitive nephrotic syndrome(SSNS). Method : We prospectively randomized the patients with nephrotic syndrome(biopsy proven or clinically compatible to minimal change nephrotic syndrome) into the albumin group(20$\%$ albumin 1 g/kg) or control group(5$\%$ D/W) between March 1997 and September 1999 at Ewha University Mokdong Hospital. We compared the clinical course of the albumin group(n=13) with the control group(n=13). Results : 1. The duration of steroid therapy until complete remission in the albumin group was significantly longer than the control group($13.7{\pm}6.4\;days\;vs\;7.5{\pm}2.8\;days$)(P<0.05). 2. The remission duration to the first relapse was significantly shorter in the albumin group ($94{\pm}63.5$ days) than the control group($190{\pm}106.4$ days)(P< 0.05). There was no significant difference in the relapse rate within 1 year after complete remission[77$\%$ (10/13) vs 46$\%$ (6/13)](P>0.05) and the relapse frequency per year($1.9{\pm}0.8\;vs\;1.5{\pm}0.5$) between the albumin and control groups. 3. Spot urine protein/creatinine ratio significantly increased in the albumin group at post-albumin 2, 4 days(P<0.05). There was no significant difference in the change of the daily percent weight loss, blood pressure, serum Na, K concentration between the albumin and control groups. Conclusion : Albumin infusion in SSNS delayed the response to steroid and shortened the remission duration to the first relapse. Albumin should be carefully used in nephrotic edema.

This study was conducted to determine the effects of dietary supplementation with probiotics on the growth and meat quality of finishing pigs. A total of forty eight ($Landrace{\times}Yorkshire{\times}Duroc$) pigs ($55.3{\pm}1.5 kg$ average initial body weight) were randomly assigned to four groups and fed on a diet supplemented with 0, 0.2, 0.5 or 1% probiotics for 58 days. The pigs were slaughtered at approximately 105 kg live weight. Supplementation with 0.2% probiotics significantly (p<0.05) increased daily gain compared to the control. The daily gain of pigs in the 0.2% probiotic group was 0.95 kg whereas that of the control was 0.85 kg. The average feed intake was 2.79-2.84 kg and there were no significant differences in feed intake between the control and test groups. The feed conversion of the 0.2% probiotic group was 2.96 kg whereas the control showed a feed conversion of 3.28 kg. The results of this study imply that supplementation with 0.2% probiotics may improve the feed conversion of pigs. There were significant differences in carcass weight, carcass ratio, backfat thickness, and frequency percentage of A grade carcasses between the control and probiotic test groups. In addition, the moisture, crude protein and crude ash contents of the probiotic treated groups did not differ significantly from the control group, however the crude fat values of the 0.2% probiotic test group was significantly tower than the other groups. The muscle pH levels of all samples ranged from 5.63-5.67 which is the normal pH of pork. The supplementation of probiotics resulted in decreased lightness ($L^*$) values and increased redness ($a^*$) values. Furthermore, the saturated fatty acid contents of the 0.2% and 0.5% probiotic test groups decreased and the unsaturated fatty acid contents increased relative to the control.

Purpose : This study was performed to determine the clinical and epidemiologic characteristics of nosocomial rotavirus gastroenteritis. Methods : We retrospectively analyzed 628 medical records of patients with rotavirus gastroenteritis between 2001 and 2005. The patients were divided into two groups (the community-acquired group [528 cases] and the nosocomial group [100 cases]. The epidemiologic and clinical indices between the groups were analysed. For clinical comparison, 100 agematched cases were selected from the community-acquired group. Results : The male-to-female ratio was similar (1.4:1 vs. 1.5:1), but the mean age was lower in the nosocomial group compared to the community-acquired group (21.9${\pm}$15.5 months vs. 16.6${\pm}$10.3 months, P <0.001). The patterns of age distribution, annual frequency, and seasonal distribution were similar in both groups. The proportions of nosocomial cases in each year ranged from 9.8% to 22.4% of annual rotaviral infections, and these were not proportional to annual cases. The duration of fever appeared more prominent in the nosocomial group, and the severity of diarrhea was not different between the groups. The cases with a BUN >20 mg/dL were more in the community-acquired group (16% vs. 4%, P=0.01). Conclusion : The clinical and epidemiologic charateristics of nosocomial rotavirus gastroenteritis were similar and correlated to those of the community-acquired gastroenteritis.

Occasionally, We make mistake of discrimination of sex since a pair of small spots around tile abdomen of 9th abdominal of males and posterior spots of females of the silkworms larvae are found at almost same position. As already have reported, more larvae which have the small spots were found in Chinese race than the Japanese. This research has been conducted in order to grasp the rate of appearance of the small spotted larvae hereditarily when hybridize with different race (F$_1$) 1. According to the first report, average 17,8％ of the small spotted larvae are found in the Japanese race and 57.0％ in the Chinese, but my re-invested data which was carried out recently shows that average 13.6％ in the former case and 37.8％ in the latter. Those new data are supposed to be come to a conclusion that the figures are flexible but in any case high frequency of appearance of the larvae were found in the Chinese race than the Japanese (Reference Table 1 ) 2. Miscalculated ratio of the larvae from males to females are 1.2-2.6％, and from females to males are found 0.5％-0.9％ in the Japanese race, In case of the Chinese race, 7.1-9.4％ in tile former and 2.9-3.4％ in the latter. Those data also shows that more of the larvae found in Chinese race. 3. The larvae of small spotted and non-spotted are also seperated when hlybridize with different mating types and races. 4. More small spotted larvae are seen when hybridize with less appeared of the small spots of females and males which have the small spots than more appeared of the small spots of females with none spotted of the males (Reference Table 2. C.G.)B.F.). 5. More larvae of the small spots and found in case of hybridize in a group of having small spots than none of the spots (H>E). 6. With the exception of the case (A.B), in the same type of cross breeding (C.D, E.F, G,H), more larvae of the smal1 spots are also found in case of hybridize with males of having the spots than none of the spots.

In this research, we have analyzed the impact factors on the bone mineral density thru the examination of bone density difference in the entire femur, femoral neck and lumbar of adult women before the menopause in accordance with the general features, lifestyle, eating habits, health and body composition. The survey was conducted among adult women before the menopause and older than 30 years based on the data of the National Health and Nutrition Examination Survey carried out in the 4th term (2008-2009) and 5th term (2010-2011) and we would like to provide the research results for the establishment of recommendations or guidelines for the treatment of adult women before the menopause with regard to the impact factors on the bone mineral density and for the development of health education materials for the accurate measurement of bone mineral density of young women in order to prevent the postmenopausal osteoporosis. With respect to the general features of adult women before the menopause, the bone mineral density was higher in the entire femur at age 40-44, femoral neck at 35-39, in high-school education level, in the earlier menarche group, without smoking experiences, with regular walking time and exercise frequency and with the habits of eating no hamburger or pizza. With regard to the body composition, the bone mineral density was higher in obesity and lower in underweight cases, higher among people with abdominal obesity and weight control experiences. In terms of total body fat ratio, total amount of fat and muscle, the bone mineral density got gradually increased from the 1st quarter (Q1) to the 4th quarter(Q4). The obesity, disease, total amount of fat and muscle were shown to be significantly related with the bone mineral density in this research and it is required for young women to keep the adequate weight and the normal BMI in order to increase the bone mineral density. For the prevention of osteoporosis, it is advised to keep the right habits including regular exercise and no smoking discipline from the growing period and achieve the maximum bone mass thru the control of proper weight from a young age.

Purpose : Because infants who have been hospitalized in the neonatal intensive care unit (NICU) are usually ill or premature, they are hospitalized repeatedly after their discharge. We intended to survey the frequencies and the medical costs of those rehospitalizations. Methods : The NICUs of 7 major hospitals were included. The subjects were 3,451 infants that were admitted to the NICU from July 2005 to June 2006, and discharged to home. The frequency, causes, mean cost and distribution and proportion of National Health Insurance coverage and non covered costs were analyzed. Results : The rate of rehospitalization after discharge from the NICU over 1 year was 14.8%. If multiple cases are considered as individual cases, it is 21.7%. The major causes of admission were pneumonia (15.8%), bronchiolitis (14.5%), gastroenteritis (10.4%), urinary tract infection (6.3%) and sepsis (6.3%). The mean cost for each admission was 1,652 thousand won. The mean cost of National Health Insurance coverage was 1,170 thousand won and non covered coat were 472 thousand won 70.9% and 28.6% respectively. Conclusion : The ratio of rehospitalization of infants after their discharge from the NICU over 1 year was approximately 20% and it means that follow-up management of these infants is very important and meticulous concerns after discharge should be given. However the rehospitalization and the non-coverage proportion of National Health Insurance cost is considerably high. It strongly implies that National Health Insurance should cover much more proportion, and personal cost exemption should be proceeded in case of rehospitalization of infants after discharge from the NICU.

Purpose: The purpose of this study was to evaluate the long term outcome and the factors contributing to treatment outcome for chronic functional constipation in children. Methods: Sixty three children were enrolled who had chronic functional constipation and could be followed by telephone contact. They were treated at the Bucheon Soonchunhyang Hospital for more than 1 month and observed from March 2001 to June 2005. We analyzed the clinical features, symptoms and signs, as well as the course and results of treatment. Results: The male to female ratio was 35 (55.6%) : 28 (44.4%). The mean age at the onset of symptoms and diagnosis was $21.1{\pm}23.5$ (1.9~84.0) months and $47.1{\pm}34.2$ (6.9~138.0) months, respectively. The mean defecation frequency before treatment was $3.2{\pm}2.3$ (0.5~10.0) times per week. The symptoms associated with constipation were as follows: soiling 34 (54.0%) which was more common in males than females, large stools in 30 (47.6%), decreased bowel movements less than three times a week in 20 (31.7%), straining during defecation in 19 (30.2%) and retentive posturing 19 (30.2%). The mean duration of follow-up was $34.2{\pm}14.6$ (3.6~60.0) months and 44 (69.8%) patients had their symptoms resolve ("success") and 19 (30.2%) were not resloved ("fail") from the constipation. The time for recovery from soiling, straining during defecation and retentive posturing after treatment was $4.3{\pm}2.4$ (1.0~36.0), $5.0{\pm}1.4$ (0.8~36.0) and $5.0{\pm}3.1$ (1.0~36.0) months, respectively. A relapse of the constipation occurred in 15 (23.8%) patients, 9 (60%) boys and 6 (40%) girls. The time to relapse after cessation of treatment was $2.9{\pm}1.9$ (1.0~6.0) months and the only risk factor associated with relapse was the initial duration of treatment. Conclusion: Most of the patients had resolution of symptoms within five months after treatment; relapse occurred within three months after the interruption of treatment. The duration of treatment was important for recovery and for the prevention of relapse in the constipated children. Thus a long term maintenance of therapy and follow-up is necessary for chronic functional constipation in children.

This study was performed to investigate the distribution and differentiation of choline acetyltransferase (ChAT)-immunoreactive cells in the basal nucleus of Meynert of the postnatal and adult rat forebrains, utilizing techniques of immunocytochemistry. According to the cell shape and the ratio of long axis vs short axis of cell soma, the ChAT-immunoreactive nerve cells in the basal nucleus of Meynert of the adult rat were classified into six types. In the adult rat, the frequency distributions (FD) of round, oval, elongated, fusiform, triangular and polygonal cells were 9.4%, 35.5%, 32.1%, 5.9%, 9.1% and 8.0%, respectively. The FD of oval and round nerve cells on the postnatal day (PND) 14 were observed to be 18.7% and 51.5%, respectively. Those were shown to be progressively decreased during developmental process to the adult. Also, those of elongated and triangular nerve cells on the PND 21 were observed to be 30.4% and 10.1%, respectively. Those were shown to be same phenomenon a,1 those in the round and oval cells. Meanwhile, those of the triangular and polygonal nerve cells were progressively increased from the early postnatal stage to the adult. The total mean volumes of ChAT-immunoreactive cell somata in the PND 7 rat were the lowest $(1,083{\mu}m^3)$ and those in the PND 21 rat were shown to be the highest $(5,045{\mu}m^3)$. But in the adult, those were decreased to $(2,731{\mu}m^3)$. Those in the PND 21 rat were shown to be about 84.7% larger than those in the adult. On the electron micrography, the cell organelles such as ribosomes, polysomes, rough endoplasmic reticula (RER) and mitochondria were well developed in the PND 21 rat forebrains, but Golgi complexes were shown to be proliferating phase. Especially, ribosomes, polysomes and RER were immunoreactive in the tissues treated with 0.05% triton X-100. According to the observations in the present study, it is considered that the ChAT-immunoreactive nerve cells in the basal nucleus of Meynert of the rat forebrains are differentiated throughout the following processes of changes during the postnatal development: 1) increase of cell soma volumes with the differentiation of tell organelles and neurites, 2) increase in the FD of differentiated tell types and 3) cell schrinkage without cell loss. The ribosomes, polysomes and RER are considered to be closely related to the intracellular localization and biosynthesis of the ChAT but not Colgi complex.
